Abstract

This paper describes in detail the formulation of large strain solid mechanics based on the tensor cross product, originally presented by R. de Boer, Vektor- und Tensorrechnung für Ingenieure, Springer-Verlag, 1982., page 76, and recently re-introduced by Bonet et al. in J. Bonet, A. J. Gil, R. Ortigosa, A computational framework for polyconvex large strain elasticity, Computer Methods in Applied Mechanics and Engineering 283 (2015) 1061 – 1094., and J. Bonet, A. J. Gil, C. H. Lee, M. Aguirre, R. Ortigosa, A first order hyperbolic framework for large strain computational solid dynamics. Part I: Total Lagrangian isothermal elasticity, Computer Methods in Applied Mechanics and Engineering 283 (2015) 689 – 732. The paper shows how the tensor cross product facilitates the algebra associated with the area and volume maps between reference and final configurations. These maps, together with the fibre map, make up the fundamental kinematic variables in polyconvex elasticity. The algebra proposed leads to novel expressions for the tangent elastic operator which neatly separates material from geometrical dependencies. The paper derives new formulas for the spatial and material stress and their corresponding elasticity tensors. These are applied to the simple case of a Mooney-Rivlin material model. The extension to transversely isotropic material models is also considered.
